MAIL RECEIVIHG AND lDELIVERING APPARATUS.

To all whom it may concern;

1 Bev it known thatL-Pia'rnn A. BLoMnnRo, a eifizen of the United States, residing at Jesse Lake, in the county of Itasca and. State of Minnesota, have invented certain new and useful Improvements in Mail Receiving and Delivering Apparatus, of which I the following is a specification, referencebeing hadtherein to the accompanying drawing 1 v V v This invention relates to mail bag delivering and'receiving apparatus and has for its object the production of an'efiicient means 'whereby mail bags may be delivered to and received from a fast moving train, without injuring the mail bags.

'Another object of this invention is the production of an efiicient means whereby the mail receiving and also mail deliver ng arms may be adjusted to the desired position for receiving and delivering mail sacks.

" Other objects and advantages of the presentdevice will appear throughout the folloWing specificationand claims, and, of

course, it should be understood. that the present device may be modified as to its detail mechanical structure without (ilepartingfrom the spirit of the invention.

In the drawings :Figure 1 is a perspective View of the mail car in the act of doliv ering and receiving mail bags. Fig. 2is a top plan View of the mail delivering and receiving apparatus which is adapted to be placed to the side of the railroad track,

showing the mail car in section. Fig. 3 is a vertical section of the ma l delivering and receiving standard which is adapted to be positioned to one side of the railroad track. Fig.4 is a transverse section through one of the mail bag supporting and receiving fingers showing the construction of the retaining'notches formed therein. Fig. ,5 is a detail perspective of one portion of a mail bag supporting loop.

The mail receiving and delivering device which is carried. to the side of the rail-road track comprises a platform 1 upon which is Jmounted an elevated platform 2 for allowing access to be had to the mail receiving arms carried by the crane 3. This crane 3 comprises a substantially rectangular body having angle ends 4 for facilitating the curing of said crane 3 to the support 1'.

Steps 5 are employed upon the platform 2 for allowing the operator to easily climb Application filed August 2,1913. Serial No 782,659.

from the platform 1 to the platform 2." The crane?) is provided with a plurality of aperturese for greatly reducing the Weight of said crane. As illustrated in Figs. 11 and 3 ,of the drawings the crane taper's toward its upper end and carries a reinforcing cap 7 within which is journaled the threaded shaft 8 of the operating wheel 9. .This shaft 8 engages at its lower end an angle extension 10 ofjghe depending end 11 of the' mail bag receiving and delivering arm 12. The depending end 11 of the mail receiving and. delivering arm 12 works in a bracket 13 car .ried by'the inside of the crane 3. The arm 12 is'preferably rectangular in cross section,

and works in a rectangular aperture 14 so that'the arm will be held against rotation.

Mailba supporting and receiving frame 15 is carried by the outer end of thearm 12 liiid comprises a pair of looped portions 16 which are adapted to receive the mail bag after "thesame has been delivered thereto,

and vertical extending members 17 which act as abutment means for the mail bag supporting hooks. An arm 18 extends from each of the loop portions 16 and is adapted to receive a support or mail bag supporting hooks 19. These arms 18 are provided with a plurality of notches 20 for facilitating the holding of said mail bag supporting hooks 19 in their proper position.

From the foregoing description it will be obvious that by turning the operating wheel 9, a vertical adjustment of the supporting and receiving arm 12 may be obtained to accommodate diii'erent height cars which may pass over the road.

Mail bag supporting hooks 19 are carried by the arms 18 as previously stated and these hooks are. of a substantially rectangular shape carrying upon one side thereof an overhanging hook 21. This hook 21 fits snugly within the notches 20 formed in the arms 18 and these notches not only extend upon the top of the arms 18 but also extend upon one side thereof so that the mail bag supporting hooks will be held in their cor rect relation to be taken off by the cooperating arm carried by the car. A bag gripping clip 22 is carried near the bottom of the hook 19 and. this hook constitutes an overhanging end 23 which straddles the vertical 19. By having the mail bag supporting clip 22 en 'a in the vertical ortion 24 of the e g e P vertical mail bag supporting hook 19 it will be obvious that the bag will be firmly held in engagement with the hook 22 and may also easily be released when so desired.

The apparatus which is carried by the car comprises a delivering arm 25 having an' adjustable outer end 26 which outer end is provided with a pair of laterally extending arms 27 and 28 terminating in loop portions 29 and 30 at their inner ends. The adjustable outer end 26 may be adjusted by means of an operating wheel 31 which is provided "with a threaded stem for engaging the 'adjustable end 26. This delivering arm 25 may be swung within the car to the position shown in dotted lines in Fig. 2 when it is so' desired.

Having thus described the invention whatis claimed as new, is

1. A mail delivering and receiving apparatus comprising a stationary crane, said crane constituting a substantially rectangular body tapering toward its upper end, a mail bag delivering and receiving arm car ried thereby, and an adjusting screw carried by said frame and cooperating withsaid arm for raising and lowering the same as said'screw is rotated.

52. A mail bag delivering and receiving apparatus comprising a standard, a mail bag delivering and receiving arm vertically ad ustable therein and being provided with an overhanging end, laterally extending fingers formed upon said arm each of said fingers being provided wit; notclnr, said fingers terminating at their inner ends in a loop vportion, an abutment finger adjacent said loop portion and said abutment finger being adapted to retard the motion of a mail bag supporting book while being placed upon said finger,

In testimony whereof I hereunto affix my signature in presence of two witnesses.
